... Study of Mg-Fe-silicate glasses of variable composition. ... With the new data, the astrophysical discussion started in Paper I was continued and focussed on the comparison of the olivine glass data with IRAS LRS spectra of O-rich circumstellar envelopes around Mira stars. ... The new olivine glasses point to the interesting consequence that the temperature for silicate dust grains at the inner edge of circumstellar envelopes must be considerably higher than the values often given in the literature....

Next: Imaging Polarimetry with NICMOS Up: NICMOS Data Calibration and Previous: The Photometric Performance of . ... NICMOSlook and Calnic C . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... NICMOSlook and Calnic-C are two programs that were designed to take advantage of the fact that the NICMOS grism mode typically consists of taking both a direct and a grism image. ...

These noctilucent "night-shining" clouds (or NLCs) are believed to form by sunlight reflecting off ice crystals high in the atmosphere, and usually appear in the northwest to northeast. ... NLCs occur at very high altitudes, in excess of 50 miles high, in the region above the stratosphere known as the mesosphere and at first sight they look like cirrus clouds. ...

As an obligatory preparing for the application to participate in the IAO a short report of National Olympiad of the current year with a set of all problems used on the Olympiad has to be presented by the applicating team. ... The final minutes (protocols written in Latin or Cyrillic in form of tables) of the Olympiad (evaluating of solutions of the students participated in the last stage of the Olympiad) should be included as well. ...

Allows you to specify a drift scan: motion at a constant velocity along a great circle. ... The path starts at the new object position (though the telescope actually intersects the path later, see Subtleties ). ... Note that the units are always /sec for both axes. ... The velocity along the path is 0.01 /sec. ... The path is assumed to start when you hit the Slew button (more precisely, when the TCC parses the command). However, it takes the telescope awhile to slew to meet the specified path. ...
